[0040] Reference Figure 1 , Figure 3 As shown, an aviation multi-electric control system test explosion-proof cabin of the present invention comprises: The cabin is provided with a receiving cavity capable of receiving the test piece; At least one mounting bracket 33 is disposed in the accommodating cavity, the mounting bracket 33 comprises a plurality of bracket mounting surfaces 331, wherein at least two of the bracket mounting surfaces 331 are not on the same plane, and the bracket mounting surfaces 331 are distributed with mounting holes 16, pipeline holes 18 and cable holes 19; A pipeline 14, used to be connected to the test piece, and an end of the pipeline 14 can pass through the pipeline hole 18; The pipeline support 13 is used to support the pipeline 14, and the support plate of the pipeline 14 is installed on the bracket installation surface 331 through the safety control hole; A pipeline fixing member 32 connected to the pipeline support member 13 and confining the pipeline 14 on the pipeline support member 13; A cable, used to be connected to the test piece, and an end of the cable can pass through the cable hole 19; The cable support 12 is used to support the cable.

[0041] In one embodiment, referring to Figure 4 As shown, the mounting bracket 33 includes three bracket mounting surfaces 331 , the three bracket mounting surfaces 331 are connected in sequence and two adjacent ones are perpendicular to each other, and an area for placing the test piece is surrounded by the three bracket mounting surfaces 331 .

[0042] The mounting bracket 33 provides a plurality of bracket mounting surfaces 331 that are not on the same plane, which can adapt to different pipeline networks 21 and can meet the installation requirements of various complex test pieces, thereby improving the applicability and installation flexibility of the system. In addition, the bracket mounting surface 331 is provided with mounting holes 16, pipeline holes 18, and cable holes 19, which facilitate the installation of various equipment, pipelines 14, and cables, and simplify the wiring and pipeline 14 design during the test.

[0043] In one embodiment, referring to Figure 2 , Figure 3 , Figure 8 As shown, the bracket mounting surface 331 includes a first area and a second area in the vertical direction, the cable holes 19 are distributed in a rectangular array in the first area, and the pipe holes 18 are distributed in a rectangular array in the second area. The mounting holes 16 are threaded holes, including first mounting holes 161 and second mounting holes 162. Each row of the cable holes 19 is provided with a row of the first mounting holes 161 on one or both sides of the longitudinal direction, and each row of the pipe holes 18 is provided with a row of the second mounting holes 162 on one or both sides of the longitudinal direction.

[0044] The cable holes 19 and the pipe holes 18 are distributed in a rectangular array, which not only facilitates the arrangement of cables and pipes 14, but also provides efficient access and outgoing line management, simplifying line planning during installation. Through different areas, the distribution of cable and pipe holes 18 can be flexibly adjusted according to different needs, ensuring that the cables and pipes 14 of the test system are neatly arranged.

[0045] In one embodiment, referring to Figure 5 As shown, the pipeline 14 includes a first pipeline 141 and a second pipeline 142, the first pipeline 141 includes a first straight section and first plug-in sections extending perpendicularly to both ends of the first straight section, and the two first plug-in sections can be inserted into the pipeline hole 18 on the same bracket mounting surface 331; The second pipeline 142 includes a curved section, which includes a second straight line section parallel to the two adjacent bracket mounting surfaces 331, and a second plug-in section extends vertically along one end of each of the two second straight lines. The two second plug-in sections can be inserted into the pipeline holes 18 on the two adjacent bracket mounting surfaces 331.

[0046] In one embodiment, referring to Figure 6 As shown, the cable support 12 includes a first connecting plate 121 and a second connecting plate 122 that are perpendicular to each other, first connecting holes 123 corresponding to the first mounting holes 161 are distributed along the length direction of the first connecting plate 121, hollow grooves 124 are spaced apart along the length direction of the second connecting plate 122, and a baffle 125 is vertically extended from one end of the second connecting plate 122 away from the first connecting plate 121.

[0047] The cable support 12 can ensure that the cables are routed in an orderly manner on the mounting bracket 33, avoiding cable entanglement or interlacing that affects the operation of the test piece. The cable routing through the cable hole 19 effectively reduces the clutter of the cables, improves the neatness of the internal space, and facilitates maintenance personnel to perform inspections and troubleshooting during the test. In addition, the physical separation and support design of the cables can prevent the cables from being interfered by external forces, ensuring the stability of electrical signal transmission.

[0048] In one embodiment, referring to Figure 7 As shown, the pipeline support 13 includes a first connecting plate 131 and a second connecting plate 132 that are perpendicular to each other, and second connecting holes 133 corresponding to the second mounting holes 162 are distributed along the length direction of the first connecting plate 131 .

[0049] Reference Figure 5 As shown, the pipeline fixing member 32 includes an arc-shaped fixing portion 321 and mounting edges 322 extending along both sides of the arc-shaped fixing portion 321. The pipeline 14 is suitable for passing through and contacting the arc-shaped fixing portion 321. A mounting groove 134 extending along its length direction is provided along the second connecting plate 132. The mounting edge 322 is provided with a connecting groove 323. The connecting groove 323 and the mounting groove 134 are matched through a connecting member.

[0050] The pipeline support 13 and the fixing part ensure the stable installation of the pipeline 14 on the bracket, and at the same time, the pipeline network 21 can operate efficiently during the test by passing through the bracket through the pipeline hole 18. This design can prevent the displacement or damage of the pipeline 14 due to vibration or external force, ensure the safety and stability of the pipeline 14, and further improve the reliability of the system. In addition, the cooperation between the pipeline support 13 and the pipeline fixing part 32 can provide sufficient support and flexibility for the complex arrangement of the pipeline 14, and avoid the damage of the pipeline 14 due to excessive force.

[0051] In one embodiment, referring to Figure 4 As shown, the mounting bracket 33 is provided with a bracket fixing edge 22 extending vertically from the bracket mounting surface 331 and used for being mounted in cooperation with the bottom of the cabin.

[0052] Reference Figure 1 , Fig. 9 , Fig.10 As shown, the cabin body includes a bottom mounting plate 1, and the bottom mounting plate 1 also includes an oil hole structure, and the oil hole structure includes an internal oil leakage hole 27 and an external oil leakage hole 30 that are interconnected, an internal oil return connection hole 15 and an external oil return hole that are interconnected, and an internal oil supply connection hole 17 and an external oil supply connection hole 3 that are interconnected; The external oil leakage hole 30 is provided with an oil leakage valve 2; It also includes a third pipeline 31, which can be connected to related devices for oil supply or oil return. The bottom mounting plate 1 is a hollow plate and is provided with bottom reinforcing ribs 28 that are distributed in a horizontal and vertical manner. At least part of the bottom reinforcing ribs 28 is a hollow structure. The third pipeline 31 is partially arranged inside the bottom reinforcing ribs 28 with a hollow structure. The third pipeline 31 is used to connect the internal oil return connection hole 15 and the internal oil supply connection hole 17. A sealing welding structure 29 is provided between the third pipeline 31 and the internal oil return connection hole 15 and the internal oil supply connection hole 17.

[0053] Through the above arrangement, the oil hole structure design of the bottom mounting plate 1 makes the oil circuit system more integrated and compact, reducing the complexity of the external pipeline 14. The sealing welding structure 29 between the internal oil return and oil supply connection holes further ensures the airtightness of the oil circuit, prevents oil leakage, and improves the stability of the system.

[0054] In one embodiment, referring to Fig.11As shown, the cabin body also includes a top mounting plate 34 and a side mounting plate 35. The side mounting plate 35 is provided with a quick-connect ring 8 (quick plug, explosion-proof plug, which is an existing component) at the peripheral end. The top mounting plate 34 is provided with top reinforcing ribs 25 distributed in a horizontal and vertical staggered manner. The top mounting plate 34 is also provided with a top cable support plate 24, a cable lowering main groove 23 and a cable lowering spare groove 26. The top mounting plate 34 includes a frame, a plurality of cover plates 10 arranged on the frame, and an inner cover plate 9 connected to each of the cover plates 10.

[0055] The top cable support plate 24 provides good support for the orderly arrangement of cables, and is convenient for installing cameras for real-time monitoring during the test. This is helpful for ensuring the working status of the test piece and cables, improving the safety and controllability of the test process, and reducing unexpected situations during the test.

[0056] In one embodiment, referring to Figure 1 As shown, the side mounting plate 35 is provided with explosion-proof glass windows 6 and explosion-proof doors 7, the bottom mounting plate 1 is provided with movable rollers 5, and the explosion-proof doors 7 are provided with observation windows 11. The design of the explosion-proof windows and explosion-proof doors 7 provides a guarantee for safety protection during the test and prevents the leakage of explosion shock waves. The bottom-mounted rollers make the explosion-proof cabin have good mobility, which is convenient for test personnel to quickly adjust the test position according to needs, and improves the flexibility of the equipment.

[0057] Through the above arrangement, the cable support 12 is fixed on the mounting bracket 33 and is located outside the bracket; the pipeline 14 is installed on the mounting bracket 33 through the pipeline fixing member 32 and the pipeline support member 13; the interior of the mounting bracket 33 is mainly used to place the test piece, and the pipeline 14 and the cable are distributed between the outside of the bracket and the inside of the explosion-proof cabin. A single pipeline 14 extends from the pipeline hole 18 to the inside of the bracket through the fluid inlet and outlet on the pipeline fixing member 32, and the inlet and outlet of the pipeline 14 are flush with the inside of the bracket (without affecting the installation of the test piece), thereby forming a pipeline network 21. The cover plate 10 and the inner cover plate 9 on the top of the test cabin can be opened; after opening, the cable support plate on the top can be seen, and the cable support member 12 (cable support plate) is used to carry the cables connected to each quick-connect ring 8, quick-connect plug and explosion-proof plug, as well as various electrical equipment (such as power management instrument) inside the explosion-proof cabin. The cables enter the explosion-proof cabin through the cable tray, are located outside the mounting bracket 33, and are placed on one side of the cable tray and the pipeline 14 tray; then the cables are arranged on each tray in layers, and the cable ends are passed through the cable holes 19 to form a cable network 20.

[0058] After the test piece is installed, it is connected to the nearest cable connector, and at the same time, it is connected to the inlet and outlet of the pipeline 14 through the designed pipeline 14 connection tooling; for test pieces that are far away, the pipeline network 21 can be extended through the spare pipeline hole 18, and the long-distance connection of the inlet and outlet of the pipeline 14 can be completed internally through the connection tooling without occupying the internal space of the bracket. This design customizes the pipeline fixture 32 according to the interface characteristics of different test pieces, combined with the size of the test piece and the diameter of the pipeline 14 in the pipeline network 21.

[0059] The bottom mounting plate 1 is designed with built-in oil supply pipeline 14 and oil return pipeline 14 to save internal space as much as possible and keep the system clean; the oil supply and oil return pipeline 14 are tightly combined with the frame structure of the bottom mounting plate 1 through sealing welding to prevent the end of the pipeline 14 from exceeding the frame and avoiding external collision and friction. The bottom mounting plate 1 is also designed with an oil leakage hole and equipped with an oil leakage return valve to ensure that the test piece has an oil return function when it leaks oil. At the same time, the threaded hole of the bottom mounting plate 1 also provides an emergency solution for temporary installation of the test piece.

[0060] It should be noted that the explosion-proof cabin and its internal test pieces can be installed externally as an independent whole, avoiding site restrictions. At the same time, the explosion-proof cabin supports rapid switching of different projects, improving the efficiency of external test equipment. In the explosion-proof cabin, effective electrical isolation is achieved between the weak-current electrical devices of the intelligent node and the strong-current electric pump, avoiding mutual interference of signals. The design of the pipeline network 21 and the cable hole 19 physically isolates the pipeline 14, cables (oil lines and circuits) from the test pieces, simplifies the difficulty of connecting the pipeline 14 and cables, and effectively solves the problem of complex interweaving of test pieces, cables and pipelines 14, making the interior of the explosion-proof cabin tidier and improving the efficiency of test preparation and troubleshooting. At the same time, the vertical bracket successfully simulated the test scenario of the field engine test bench.

[0061] The explosion-proof cabin provides a stable verification environment for the internal test pieces and ensures the safety of the external space. The quick-connect ring 8 and the quick-connect plug enable the connection of the oil source main oil circuit, the power supply main circuit and the signal bus, while the internal pipeline 14 and line design ensure the effective distribution of electric energy and fuel oil. The switchable design of the explosion-proof cabin significantly improves the test efficiency, increases the utilization rate of the test platform (including power supply, monitoring platform and oil source), and eliminates the restrictions of the test space on the test piece installation process. The installation of the test piece and the pipeline can be completed in a safe and open environment, and then the explosion-proof cabin can be moved to the test space for switching and testing, thereby improving safety and flexibility.

[0062] In addition, the mounting bracket 33 inside the explosion-proof cabin integrates the pipeline network 21 and the cable hole 19 network, and appropriately physically separates the test piece, pipeline 14 and cable, reducing physical interference and improving the recognizability and cleanliness of the test environment.

[0063] When making the layout, before the test, according to the test outline, the structural design of the explosion-proof cabin and the mounting bracket 33, the pipeline 14 network, the cable network 20 and the test piece installation position are designed to obtain the installation plan of the tester.
